FLUE-CLEAN ER.

Specification of Letters Patent.

Patented Oct. 12, 1920.

Application filed May a. 1920. SerialNo. 378,507.

To all whom it may concern Be it known that I, CARL I-I. RYBERG, a citizen of the United States, and residing at Seattle, in the county of King and State of IVashington, have invented certain new and useful Improvements in Flue-Cleaners, of which the following is a specification.

This invention relates to improvements in pipe cleaners for cleaning fiue pipes, boiler pipes, etc. 7

An object of the invention is to provide a device for cleaning the exterior of the flue pipe and which is adapted to clean portions of the pipes which are ordinarily. inaccessible.

The invention comprehends improvements in the details of construction and operation which are more particularly pointed out in the following description and claim.

In the drawings:

Figure lis a perspective view of the device.

Fig. 2 is a side elevation of the invention in operative position on a flue pipe, another position of the device being shown in dotted lines.

Fig. 3 is a sectional view on line 3-3 of Fig. 2.

1 indicates a semi-circular yoke, the inner edge 2 of which forms a scraping edge. Intermediate the ends of said yoke a handle 3 is formed integral therewith and extends at substantially right angles thereto. A movable scraper member 4: is provided witha slot 5, and a handle 6 is secured to one end.

This member is mounted on the yoke l by a bolt 7 which passes through the slot in said member at. The member 4 as shown in the drawings is of arcuate shape and the inner edge 8 1s adaptedto coact with the edge 2 to lengthen the scraping surface of the device.

In using this invention the yoke 1 is placed on a flue pipe 9 as shown and is pulled back and forth on said pipe which will scrape the soot from the upper half of the pipe. Then the movable scraper member is moved to its extended position as shown in Fig. 3, and the scraper again drawn back and forward on the pipe whichv will remove the dirt from half of the under side of the pipe. In order to remove the dirt from the remainder of the pipe it is necessary to change the position of the device as indicated in dotted lines in Fig. 2, then byextending the movable scraper member' it is obvious that the remaining dirt will be scraped off of the pipe.

l/Vhat I claim is:

A pipe cleaner comprising a yoke formed intermediate its ends with a handle extending laterally therefrom, one portion of said yoke being adapted to form a scraping surface, and a movable scraper member slidably mounted near one end of said yoke and adapted to form an extension on one end of said yoke.

In testimony whereof I aflix my signature.

CARL H. RYBERG.
